mn'rnon ANn rrAnArus roa PILLNG rnmoos MATERIAL.

Application filed January 2, 1926. Serial No. 78,751.

My invention has a special adaptation to the manufacture of rope whereinthe hemp is first subjected to the action of a carding wheel, or aplurality thereof, from which it is dotted and gathered and finallytransported to certain piling mechanism.

My present invention is directed to an improved piling mechanism for theorderly deposition of strips of carded fibre on a receptacle especiallyadapted for use in connection with a two-unit synchronized apparatus,but it is to be understood that it may be connected with a singlecarding machine,

or to other types ofmachines.

The object of my invention is to provide means that will reduce thenumber of attendants at each machine and to increase maappears in Fig.1.

terially the quantity of line in each part, so

' that splicing will not occur so fre ently and a better quality of ropewill be p duced.

A further object of the invention resides in the provision of means foreliminating the a twist usually found in a line of sliver and deliveringsliver to a receiver in a formation that will obviate entanglement andto increase the capacity of the receiver.

A still further object is to provide means for maintaining aco-operation between the discharging and receiving portions of a pilingmechanism.

My invention is shown e mbodied-in a distributing and piling mechanismsuitable for employment in connection with carding machines andanalogous apparatus" for piling the sliver in the course of ropemanufacture, and said invention comprises essentially meansfor impartinga wavy or zig-zag fall to said fibre through the medium of swingingplates and depositing same on an oscillating platform carrying asubstantiallyU-shaped guard-sheet, t is platform being given a retaryoscillatory motion by this mechanism and at a speed having a definiteratio to the rate at which the sliver is delivered to it.

The foregoing objectseand others that will appear as the nature 'of theinvention is better understood ma be accomplished by a construction, comination, and operative arrangement of arts such as is disclosed bythedrawings. T e nature of the invention is such as to necessarily renderthe same susceptible of various modifications, so that the showing ofthe drawings is to be considered merely illustrative, and I amentitled-to make onto a receiver, as described hereafte all such changestherefrom as fall within the scope of the claims.

In the drawings: Figure 1 is a side elevation of a portion of a cardingmachine embodying my invention. Fig. 2 is a vertical transversesectional view taken substantially on the line 22 of Fig. 1,illustrating the turning or drawing olf means and runway upon which thesliver travels to the piling mechanism.

Referring now to the drawing, A denotes the frame of the cardingmachines B, which 1s provided with the usual carding wheel C, from whichlatter the fibrous material is dofie'd, turned, and drawn for finaldeposition Referring now to Fig. 2 of the drawings, the numeral 7denotes the dofling means wherein the curvature of the inclined sides 8causes the material to gather centrall thereof. After passin turned onthe pinlO and 11. The material is now in the form of a sliver and readyfor deposition onto the receiver. A

For a clear understandingof the invention it maybe said that the termpiling mechawhich latter the fibrous material in sliver form isdeposited. The description about to under roll 9, it is conveyed to thedis- 'charg1ng'portion' 12 by means of the runway follow will firstembrace the receiver and its component parts.

Referring to Figures 9 to 11 of the drawings, a stationary base 14 onthe floor level carries on its upper surface a rotatable plate or table15. Said base 14 is provided with a gear 16 operating within a recess insaid platorm and adapted to be rotated from the vertical shaft 17 whichimparts motion to a gear 18, through a set of reduction gears 19, and

23, which embraces said circular plate 15 on three ides. The upper faceof said plate 15 is prov (led with radial cleats 15' which tend to.carry the hemp'coils or layers when they are laid on the said platewithout slippagc.

As previously pointed out, I provide mechanism for imparting a rotaryoscillatory mo-. tion to said p ate 15 as experience has proven thatthis motion co-operates with the action of certain swinging plates 13 ofthe discharging ortion 12, for the purpose of athering t e line ofmaterial and depositing it on the rotatable table 15 in a formation notonly best calculated for keeping it out of entan l'ement, but forsecuring a maximum load of bre. The mechanism for oscillating shaft 17is 'clearl shown in Figures 7 and 8 of the drawings, eing carried by theframe of the associated carding machine in close proximity to the secondcarding wheel, and is directly supported by a plate P, carrying bracket25 havm suitably ournalled therein the upper end 0 said shaft 17extending from the stationary base 14, as previously mentioned.

The-upper end of said shaft 17 is provided with a bevelled gear 26. Maindrive shaft 27 carries a bevelled gear 28, meshing with a similar gear29 and thus transmits motion the horizontal shaft 30, supported on saidplate P by means of bearings 31 and 32, which motion is communicated tothe rotatable plate 15 by means of the bevelled gears 33 and 34 looselymounted on said shaft 30. Each of said gears 33 and 34 are provided attheir inner faces with clutch members 35 and 36 which co-act with acomplementary double clutch 37, splined on shaft 30 and adapted toslidably engage said clutch members 35 and 36 at periodic intervals.

Fronithe foregoing it is apparent that the automatic engagement anddisengagement of the clutch 37 with the clutch members 35 and 36alternately connect shaft 30 to the bevelled gears 33 or 34, and thebevelled gear 26, and thus communicate a rotary oscillatory movement tosaid table 15 by means of shaft 17.

The remaining elements of the mechanism are designed to effect theperiodic operation of said double clutch 37, and to this end there is ahorizontal shaft 38, supported in bearings 39 and 40, fixed to. saidplate P. The outer end of said shaft 30 carries a sprocket wheel41.0peratively connected to said shaft 38 by means of a sprocket wheel42 and chain 43. Said shaft 38 is also provided with a bevelled gear 44,meshing with a similar gear 45 mounted on stub shaft 46, suitablysupported by means of a bracket 47 secured to the frame of the cardingmachine.

I further provide another horizontal shaft 48, extending slightly abovesaid plate P and supported thereby by means of bearing brackets 49 and50 secured to said late P, and mount on said shaft a wormeel 51,

which latter is adapted to mesh with a wormgear 52 for the pur ose oftransmitting rotative motion to sai shaft 48.

Pivotally supported from the plate P, by means of bracket 53, as at 54,is an oscillatory lever 55, having its lower end forked, as denoted at56, and adapted to embrace said double clutch 37, and having inwardlydirected pins 57 slidably engaging the annular groove 1n said clutch.The n per end of said lever 55 is provided with a follower 58,adjustably mounted in the elongated slot 55, and adapted to engage thecam groove59 in the wheel 60, fixed to said shaft 48.

It is manifest that the motion transmitted to shaft 30 from the maindrive shaft 27 is conveyed to the other two shafts 38 and 48respectively by means of the sprocket and chain arrangement and theco-action of wormwvheel 52 and worm-gear: 51. The bevelled gears 33 and34 being loosely mounted on said shaft 30, await the oscillatory swingof said lever 55, which effects the union of said shaft and the selectedbevelled gear according to the registration of the double clutch 37 withthe respective clutch members 35 and 36.

As previously pointed out, the discharging a portion of my deyice isadapted to convey the sliver, advancing along the runway 11, to thetable 15. This clevice.,(discharging portion) is further desi' ned toimpart to said sliver, as it reaches said table, a wavy or oscillatoryform of delivery through the medium of the discharging portion at aproperly ele vated position to one side of the machine.

The mechanism of said discharging device 12 is carried by a pair ofbrackets 66 suitably secured to the top portions of the arms of saidbracket 65, each of said brackets 66 bebearing 68 directly above and anupwardly extending lateral arm 69 having a bearing 70 at the topthereof. The upright parallelly disposed brackets 66 are connected byashaft a, suitably journalled in bearings 67, which carries thedischarge roller 71. It is this roller 71 that constantly exerts thenecessary pull on the sliver advancing along the runway 11 and therotation thereof is accurately timed with the carding machines, so thata smooth and constant cooperation is assured, as otherwise any unevenpull on the sliver tendsto disrupt the parallel relation of the fibres,or what is more serious, the breaking of the sliver itself.

Said roller 71 is indirectly operated from the main drive shaft 27,which carries a bevelled gear 28 meshing with asimilar gear 74 on stubshaft. 7 5, the latter being provided with a sprocket wheel 76 at itsend to which the sprocket chain 77 isconnected. The latter leads to asmall sprocket wheel 78 mounted on shaft a carrying the discharge roller71.

Frictional contact of the sliver with said roller 71 is attained bymeans of a presser roll 7 9, which further performs the function ofcompactly pressing the fibres of the sliver together for obviousreasons. This roller 79 is provided with pintles 80' mounted in saidbearings 68 and is held in contact with the sliver and the dischargeroller 71 by means of a counterweight 81 carried by arm 82 pivotallymounted in bearings of said arm 69. Links operatively connect the arm 82to the roll 79 through the medium of pintles 80.

As stated hereinbefore, the other component parts of the distributingmechanism are designed to impart a wavy or zig-zag fall to said sliverthrough the medium of swinging plates 13, which will now be described indetail.

The outer end of said shaft 0 is provided with a gear 85, adjacent tosaid sprocket wheel 78, which meshes with a similar gear 86 carried byshaft 87, supported by brackets 88.

Said brackets 88 comprise a base plate 88 suitably bolted to the bracket65, and forwardly directed bosses 89, supporting the horizontal rods 96.One of the brackets 88 is provided with an arm 90 carrying an idler 91at its end for the purpose of leading chain out of interference withshaft 87.

Shaft- 87 carrying the gear 86 is provided at its opposite end with acrank 92, which is connected with a beam 93, pivotally connected to link83, as at 94, by means of the elongated link 95.

On inspection of. Figs. 3 and 1, it will be observed that each of saidrods 96, extending from brackets 88. rigidly carries a pair of bearings97 and 98, the former pivota-lly supporting a bell crank 99, having itsupper arm connected to said beam 93 by means of link 100. The other armof said bell crank 99 is operatively connected to crank 101 by means ofalink 103. The said bearings 97 and 98 a carry shafts 10-1 and 105respectively, which lead to the companion hearings on the opposite sideof the device, said shafts supporting brackets 106 and 107 carryingswinging plates 13. As observed in the drawings, these plates extenddownwardly and terminate just short of the top of the receiving device,while their upper ends are bowed outwardly to present smooth runningedges for the sliver.

The sliver leaving the dischargin" portion 12 falls by gravity, andunder the influence of the swinging plates 13 is deposited on the table15 in a reciprocatory fashion, and were the aforesaid circular plate 15stationary, would pile thereon in a line corresponding to the diameterof said plate! However, by

. means of the mechanism just described, I also impart a rotaryoscillatory movement to said circular plate 15, so that the piling ofthe sliver is arranged in eccentric chords on said plate 15, as shown inFigure 11, and continued until the space within the guard sheet 23 isfully utilized if piled ineccentric chordal lin esthat is, offcenter-the sliver will naturally pile with an open center. This isimportant to observe, because otherwise, the sliver will hump in thecenter. and will tend to overturnthe pile, thereby decreasing the capacity of the load and causing entanglement.

Obviously under such conditions .I am enabled totake off a sliver ofgreat length within the receiving capacity of a moderatelysizedreceiver. It also serves to preserve the parallel relation of thefibres, thereby producing a better sliver, while it eliminates the costof an attendant to watch the delivery of the sliver onto the receiver.Moreover, my oscillating method of piling avoidsthe twist in the sliverthat may be produced in other methods, such, for instance, as those inwhich the receiver is completely rotated instead of oscillated. This isdue not only to the to-andfro delivery of the sliver on the table inwhat is referred to in the claims as oppositely directed lengths, butalso to the fact that whatever twist occurs as the sliver is laid duringthe time the table is rotating in one direction is off-setor neutralizedby the twist occurring as the .table is rotating in the oppositedirection. Therefore, in drawing the sliver from the pile, the twoopposite twists, which are put in the sliver'during the oscillations ofthe table neutralize eaclrother, and the sliver draws from the pile inits original condition. The sliver in my method is deposited by theto-and-fromovement of the aforesaid swinging plates in co-operation withthe to- .and-fro movement of the receiver, in a series of straight-linefolds or plies piled on top of one another. If the receiver were heldstationary, these folds would all be diametrical- 1y across thereceiver. But since the receiver ing plates is oscillated simultaneouslythe folds fall in a series ofchordal lines, as is clearly shown inFigure 11.

The term substantially straight line formation as used in the claims isintended to distinguish from ring or loop formation, and to cover anylaying of sliver in reciprocatory fashion. I

Several factors contribute to the formation of the sliver as it is sopiled. If the table is so placed relatively to the dischar e that thesliver drops near the center, it wil fall more nearly in straight lineformation and nearer the diameter of the table than it will. if droppednear the'periphery. The greater the speed of the table, the greater willbe the curve in the placement of the sliver; and inasmuch as the speedof the table is greater on the periphery than at the center,

the sliver is deposited near the periphery, the curve will be greaterthan if deposited near the center. The character of the sliver itself isalso a factor contributing to the formation of the sliver, and differentmachines operate with different speeds on fibers of different character,as will be well understood by those versed in the art.
